Status: Proposed Date: August 17, 2025 Decision Makers: PM, Chief Architect, Chief of Staff Classification: Revolutionary Bundle (includes Chain-of-Draft Integration, Ambiguity Assessment, Three-Tier Orchestration)
Our research into agent architectures revealed a fundamental insight that challenges conventional wisdom: solution path ambiguity, not computational complexity, should drive architectural decisions for single vs. multi-agent systems.
This discovery emerged from:
The convergence of these insights, combined with our MCP federation and spatial intelligence capabilities, creates a paradigm shift in how we architect Piper Morgan’s decision-making.
The economic implications require verification per ADR-015:
| Original Cost | Optimized Cost | Reduction | Verification Status |
|---|---|---|---|
| Daily standups: $15 | $0.75 | 95% | Calculated from token reduction, needs production validation |
| Sprint planning: $125 | $6.25 | 95% | Calculated from token reduction, needs production validation |
| Quarterly analysis: $2,500 | $125 | 95% | Calculated from token reduction, needs production validation |
Note: Cost reductions based on 92% token reduction from Chain-of-Draft paper (verified) applied to estimated token costs (unverified). Actual costs will vary based on model pricing and task complexity.
We will implement an Ambiguity-Driven Architecture that routes tasks based on solution path clarity rather than computational complexity, using Chain-of-Draft optimization to make multi-agent orchestration economically viable.

| “Generate test suite for auth module” | 0.85 | Single agent + CoD | Clear path but complex |
| “Improve team morale” | 0.3 | Multi-agent debate | No clear path, needs perspectives |
| “Optimize database performance” | 0.7 | Supervised multi-agent | Partially clear, needs exploration |

Note: Clarity scores are illustrative. Actual scoring algorithm to be developed and calibrated through production usage.
Description: Use computational complexity as routing criterion Rejected Because: Our research shows clear complex tasks succeed with single agents
Description: Use multi-agent for everything (Anthropic approach) Rejected Because: 15x token cost unnecessary for clear-path problems
Description: Force all problems through single agent (Cognition approach) Rejected Because: Genuinely ambiguous problems need multiple perspectives
This ADR represents a paradigm shift in our architectural thinking. The key insight—that solution path ambiguity rather than computational complexity should drive architecture—fundamentally changes how we approach PM assistance.
The economic implications are staggering: what was a $2,500 quarterly PMF analysis becomes $125, making sophisticated multi-agent analysis accessible for routine PM work.
